TOOL FOR CLOSING THE BUNG-I-IOLES OF CASKS AND THE LIKE.

Specification of Letters Patent.

Patented Dec. 31,1912.

Application fi1ed January 27, 1912. Serial N 0. 673,870.

To (LZZ whom it may concern:

Be it known that I, ANTON TUREK, a subject of the Emperor ofAustria-Hungary, residing at Salzburg, Austria-Hungary, have inventedcertain new and useful Improvements in Tools for Closing the Bung- Holesof Casks and the Like, of which the following is a specification.

My invention relates to an improved tool for closing bung holes of casksand like receptacle, and is especially applicable for inserting andpositioning in the bung holes stoppers in the form of thin hollowmetallic bungs.

The-primary object of the invention is to provide a tool of thischaracter by means of which the bung is properly and firmly positionedin the bung hole.

The drawings illustratively exemplify the form of invention which is nowpreferred by me.

Figure 1. is a vertical section through the apparatus with the thinmetal cover. Fig. 2. is a side elevation thereof. Fig. 3. is a plan ofthe apparatus. Fig. 4. is a section on AB Fig. 1. CD Fig. 1.

The apparatus for closing the hole comprises a hollow mandrel a which isdivided at its lower end into four sectors by longitudinal slits b. Thelower end of the man drel a which receives the thin metal cover 0 isformed slightly tapering and is provided with an annular projection orshoulder (Z to limit the depth to which the mandrel can enter the hole.A ram 6 is provided in the hollow mandrel a which can be presseddownward against the action of a spring f. The downward movement of theram 6 is limited by the horizontal rod 71 which passes through the slotsin the sides of the hollow mandrel a, the rod it also serves as a handlefor withdrawing the apparatus from the bung hole 1 The action of theapparatus is as follows :The thin metal cover 0 is placed on thetapering end of the mandrel a and the apparatus is placed over the hole2' as shown I in Fig. 1. By a blow on the top of the ram Fig. 5. is asection on a the whole of the apparatus is inserted in the bung hole andthe shoulder d brought against the outer edge of the bung hole 2', theram 6 moves downward in the mandrel so that all parts of the apparatusare pressed together. This causes the thin metal cover 0 to be forcedtightly against the sides of the bung hole and produces a tight closingof the bung hole especially when the latter is slightly tapering. Theram 6 is withdrawn from the hole by the action of the spring f and thewhole apparatus removed by the bar it.

The cover being made of flexible material can be employed for varioussizes of holes as its sides can be forced out to fit the correspondingsection of the hole, also any irregularities in the shape of the holewill be overcome owing to the flexibility of the thin metal cover.

What I declare as my invention and desire to protect by Letters Patentis In apparatus for closing the bung holes of easks with thin hollowmetal bungs, the combination with a hollow mandrel having its lower endtapering toward the lower extremity of the mandrel and formed of springmetal provided with a plurality of longitudinal slits, a shoulder formedcircumferentially about said mandrel imme diately adjacent the largestpart of said tapering end, said mandrel being formed with opposed slotsat diametrically opposite points in its wall, of a ram having anenlarged lower end and reciprocalole in said mandrel, a spring adaptedto normally press said ram out of operative position, and means servingas a handle and adapted to limit the movement of said ram, said meanscomprising a pin passing through said ram and extending through theslots in the wall of the mandrel.

In testimony whereof I affix my signature in presence of two witnesses.

ANTON TUREK.
